VOICE-OVER SCRIPT:

LONDON'S MORNING RUSH HOUR WAS ANYTHING BUT ROUTINE WEDNESDAY MORNING. A HELICOPTER CRASHED INTO A CRANE THEN FELL ONTO A CROWDED STREET KILLING TWO PEOPLE AND INJURING THIRTEEN.

MATT HARVERSON SHOT VIDEO ON HIS CELL PHONE THAT SHOWS HOW PERILOUSLY CLOSE THE BURNING DEBRIS WAS TO BYSTANDERS ON THE GROUND.

HE THOUGHT THE WORST AS HE HEARD THE EXPLOSION WHILE DRINKING HIS MORNING COFFEE.

Soundbite: Matt Harverson, eyewitness

It sounded like a fighter plane flying over, and we just heard a loud explosion and we thought there'd been a terrorist attack and we came straight out onto the main road.

POLICE SAY THE PILOT IS ONE OF THOSE KILLED IN THE CRASH...WHICH WAS A SHORT DISTANCE FROM A BUSY UNDERGROUND TRAIN STATION BY THE THAMES RIVER.

(SOUNDBITE (English) Neil Basu, Commander, Metropolitan Police:)

"At this stage what we believe has happened is that a commercial helicopter on a scheduled flight has collided with a crane on top of the building under construction in 9 Elms Road, South West 8. The helicopter then came down on the landward side of the building.

AUTHORITIES ARE STILL INVESTIGATING THEYES CAUSE OF THE CRASH. FIRE DEPARTMENT OFFICIALS SAY THE CRANE WASN'T IN IMMEDIATE DANGER OF COLLAPSING.
